TIRE-TIGHTENER FOR VEHICLE-WHEELS- SPECIFICATION forming part of LettersPatent No. 788,355, dated April 25, 1905.

Application filed January 21, 1905. Serial No. 242,141.

To all whom it may cmwern:

Be it known that I, ROBERT F. FRAIZER, a citizen of the United States,residlng in Cloverdale township, in the county of Putnam and I State ofIndiana, have invented certain new and useful Improvements inTire-Tighteners for Vehicleheels, of which the following is aspecification.

My invention relates to devices for tightening the tires onvehicle-wheels and to that class of tighteners carried by the wheel, andhas for its Object the improvement of devices of this character byproviding blocks with means for securing them to the ends of the tireand having screw-threaded bores to receive the respective ends of aright and left handed screw-threaded bolt. The outer ends of the boresin the blocks are made smooth to receive a shank on washers adapted tobear against the free'ends of the felly. By this construction the fellyis held in position while the tire is stretched on it in operating thescrew-threaded bolt.

The construction, operation,and advantages of my invention will be fullyexplained hereinafter and illustrated in the accompanying drawings, inwhich Figure 1 is a view of a fragment of a vehicle-wheel, showing myinvention in position; and Fig. 2, a view showing the blocks inlongitudinal section.

In the drawings similar reference characters indicate correspondingparts throughout both the views.

A represents a right and left handed screwthreaded bolthaving anenlarged central portion B, with holes 6 therein to receive a key forturning the bolt.

C C represent blocks having screw-threaded bores 0 therein to receivethe threaded portions of bolt A, the outer ends of said bores 0 beingsmooth, as shown at 0, to receive the shanks (Z of washers D.

E represents studs or projections on the blocks C C.

In securing my tightener to a vehicle-wheel a part of the felly Fbetween two spokes is cut away to receive the device, the washers Dbearing against the free ends of the felly, while the tire G is out, asshown at g, with beveled faces and the studs or projections E areclenched into holes 9 in the tire.

In operation a key is used to turn the bolt A by inserting it in one ofthe holes Z) in the central portion B. By turning the bolt in the properdirection the blocks C C are drawn together, thus tightening the tire Gon the wheel, while the washers D, being held stationary by the ends ofbolt A hearing against the ends of shanks (Z, hold the felly F fromfollowing the motion of the tire in tightening.

Having thus described my invention, what I claim is- 1. In combinationwith avehicle-wheel having the felly cut away and the tire cut oppositethereto, a tire-tightener mounted in said cut-away portion consisting ofblocks secured to the ends of the tire and having bores therethrough, apart of said bores being screwthreaded and part being smooth, a rightand left hand screw-threaded bolt to engage the screw threads in saidblocks, and washers bearing against the free ends of the felly havingshanks to [it into the smooth parts of said bores, substantially asshown and described.

2. In combination with a vehicle-wheel having its felly cut away, thetire cut opposite said cut-away portion on beveled planes and havingholes near the free ends thereof, blocks having studs integral therewithsecured in the holes in the tire, a right and left hand screwthreadedbolt, bores in said blocks having threads to engage the threads on saidbolt, the outer ends of said bores being smooth, and washers bearingagainst the free ends of the felly and having shanks to fit into thesmooth parts of said bores, substantially as shown and described.

In testimony whereof I hereto affix my signature in the presence of twowitnesses.
